Song Similarity between Neighboring American Redstarts (Setophaga ruticilla): A Statistical Analysis
Keyword(s):
Abstract We examined the hypothesis that territorial American Redstart (Setophaga ruticilla) males are geographically randomly distributed with respect to structure of the single song used predominantly before nesting. Present methods to assess the degree of similarity of song between neighboring birds are often inadequate because they do not give the level of statistical significance. We present a computer method to generate the appropriate null distribution from which the level of significance can be determined. We found statistically significant correlations between neighbors primarily in the last and penultimate discrete vocal items (phones) of the song. There were also important differences between the 2 samples.
